INCANDESCENT LAMP.

SPECIFICATION forming part of Letters Patent No. 630,862, dated August15, 1899.

Application filed J ly 23,1898. Serial No. 686,714. (No od l.)

To all whom it ntay concern:

Be it known that I, HERBERT M. COOLEY, a citizen of the United States,residing at Kansas City, in the county ofJackson and State of Missouri,have invented certain new and useful Improvementsin Incandescent Lamps;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in [Othe art to which it appertains to make and use the same.

My invention, as will be hereinafter fully described and claimed,relates to a gasoleneburner, the'object being to so utilize the gasoleneor other liquid fuel that an illuminatinggas will be generated therefromby certain parts of the burner and consumed through the mediation ofother partsthereof, whereby a brilliant light will be produced. Torender the device more effective, a mantle may be provided, if deemeddesirable, which would be rendered incandescent.

Other objects and advantages will appear from the followingspecification considered in connection with the accompanying drawings,in which Figure 1 is a side elevation of my burner complete, showingsome of the interior construction by means of dotted lines. Fig. 2 is avertical central section of the complete burner on a slightly-enlargedscale from that.

shown in Fig. 1. Fig. 3 is a bottom plan view of Fig. 1, while Fig. 4 isa detail showing the preferred construction employed for the point ofexitfor the gas, upon which the base of the frame rests. Fig. 5 is asideview of my burner on a reduced scale. Fig. 6 is a section of Fig. 5 online a a. Fig. 7 is a perspective view of the passage for the fluid 0extending around the burner and thence .to

the exit-tube.

It is obvious that by means of the damper 30 the flow of both gas andair to the burner may be partially or wholly cut off, as may be 5desired. It is evident that with the damper wide open a greater amountof air would or might enter the mixing-chamber than would be necessaryto produce the best results.

For this reason both the flow of gas and the flow of the gas and airshould be under separate control.

Briefly stated, my invention relates to means for generating a gas bymeans of heat from the fluid known as gasolene and kindred substancesand for conveying the gas thus generated to the point of combustion andcertain additional means for preventing the flame from beingcommunicated to the liquid fuel thus utilized and also for enabling theoperator to control the extent or size of the flame, as desired.

Referring in detail to the several parts of my invention and theaccessories deemed necessary in physically embodying the same, 1indicates the body-section of my improved burner, which is, as clearlyshown by Fig. 2, hollow and is preferably provided with the tubularextension upon its upper central portion, the tubular section thusprovided and the body lbeing designed to receive the tubular throat 3 ormixing-chamber, the purpose of which will be hereinafter specificallyset,

forth.

The tubular section-2 terminates at its upper end in the nozzle or rim4:, within the upper end of which I mount the guard or netting 5,preferably formed of wire or asbestos cloth and consisting of theexterior casing or section 6 and the centrally-disposed section 7,preferably disposed in the central portion of the rim 4 and retained inposition by the setscrew or rivet S, as clearly set forth in Fig. 2.

It will be seen that the tubular section 2 is provided a portion of itsextent with the inner wall or casing 9, preferably integrally formedwith the outer wall and with the body 1, thus providing the annularchamber 10, designed to extend upward as far asdeemed necessary andentirely surround the inner wall 9, thus insuring that the liquid fuel,as gasolene or the like, shall be brought sufficiently near the burnerproper, formed by the netting 5, to insure the generation of gas, itbeing understood that the tubular section 2 may be so constructed thatthe annular chamber 10 may extend very near the point of combustion, ifdeemed necessary.

The annular chamber 10 is practically a continuation, as will be seen,of the chamber or interior 11 of the body 1, the liquid fuel beingintroduced therein by the supply-pipe 12, suitably connected to the body1, as by the IOC) flange or riin 13, formed upon the underside of saidbody, a suitable point of entrance for the fuel being provided, as bythe aperture 14.

In order to insure against the possibility threads, the exit-pipe 17,which may be ining closed by the threaded bolt 23, it being.

understood that the bore designed to accommodate the needle 19 shall beof the usual size in which a needle-point is employed to regulate theflow of a fluid.

In order to render the parts neat and attractive in appearance, thehousing or outer v casing 2% may be provided, a suitable aperture beingformed in said casing to accommodate the extended end 25 of the tubularsection 20, a packing-box 26 being designed to be screwed upon the endof said tubular section, thereby confining the packing 27 in position toprevent the escape of the gas around the threaded section of the needle19. The casing 24: may be secured to the body 1 by any suitable means,'as set-screws or their equivalent, and the chimney supporting frame 28,carrying the usual standards 29, may also be secured in position bysuitable set-screws, thus rendering the interior part-s easilyaccessible.

In order that the,body 1 may be thoroughly heated during the initialprocess of preparing the burner so that it will generate its own gas, Iprovide the damper 30, of sufficient size to entirelyinclose the lowerend of the throat 3, said damper being provided with the preferablyintegrally formed flange 31, which is designed to surround and therebybe pivoted near the upper end of the exittube 17, and when thus mountedin position the damper 30 may be easily moved to either side of the'endof the tubular throat by means of the operating-handle 32, arranged toextend through a suitable slot or opening formed in the housing 24 atthis point.

By reference to Fig. 1 it will be observed that the netting 6 may beeasily formed of a section of wire-cloth, as by forcing said cloth intoa suitably-shaped recess by a plunger fitting said recess, thus causingthe section of cloth to take on the desired form and enablethe freeedges thereof to be easily'inserted in the open end of the nozzle or rim4:, it being understood that a properly-formed section of said cloth ofconsiderably less diameter than the outer section shall be provided andheld in position immediatelyover the center of the throat 3 by the screw8.

The section 7 is preferably disposed with its concave surface down, theobject in thus locating said section over the throat 3 being to deflectthe gas, and thus' cause it to spread,

and thus be properly supplied with oxygen, which can come upward throughthe throat 3, insu ringabsolutely perfect combustion thereof, thenetting 5 being also designed to insure a more thorough commingling ofthe oxygen and the gas.

It will be seen that the body 1 may be easily and cheaply formed of anysuitable material, as by casting the same, and it will be seen that itwill also be desirable to provide the lower edge of the body with anintegrallyformed flange 33, designed to provide a more reliable hearingor pointof contact for the upper edge of the housing 24: and also aseat, as by the depending ears 34, for the set-screws employed to holdsaid housing in position.

The casting is made with a circular flaring rim or flange and anintermediate rectangular part, the latter carrying a circular burner.

- In order that the body-section of my improved burner, provided withthe annular chambers 10 and 11 formed therein, may be easily cast in onepiece, it is thought that a suitable core formed of compressed sand,held together by compression by some suitable adhesive'material andhaving a suitable shape to form said chambers, may be adjusted in theouter mold and suitably suspended therein by points passing through theapertures 35 and that when the body of the burner has been formed aroundit by the use of suitable molten metal the sand forming the core may bereadily removed through the apertures 35,

as it will be understood that said core will be deemed impracticable tocast the body in one piece, as above set forth, said body may be castentirely solid, as shown in Figs. 5 and 6, in which case a suitablebore, as indicated by the dotted lines 37, is arranged to extend upwardfrom the supply-tube 38, when by properly boring the four sides of theburner near its top, as indicated by the numeral 39, a con tinuouschannel may be provided which will entirely encircle said burner when avertical bore, as indicated by 40, will provide communication from thebore 39 downward to the exit-pipe 41.

In Fig. 7 I have shown a perspective view of the several bores 37, 39,and 40 as though the same were removed from the body of the burner. Itwill, however, be understood that various methods may be employed inlocating these several bores, as it will be clear that a series of themdesigned to encircle the top of the burner may be provided, though forall practical purposes it is thought that the plan' indicated by Figs.5, 6, and 7 will be found amply su fficient. The standard 41 is designed to suspend the mantle.

It will be understood that various modifications may be adopted in theconstruction of the various parts comprising my improved lamp, and I donot, therefore, wish to be confined to the exact showing have set forth,as the equivalent of said parts is comprehended by me.

Having thus fully described the construction and advantages of myincandescent lamp by which a liquid fuel, as gasolene or the like, isconverted into a gaseous form, what I claim as new, and desire to secureby Letters Patent, is
